APPARATUS FOR USE IN DECOMPOSING METALLIC SALTS AND DESULPHURIZING ORES.

SPECIFICATION forming part of Letters Patent No. 416,316, dated December 3, 1889.

Application filed May 9, 1889. Serial No. 810,075. (No model.)

To all whom it may concern:

Be it known that we, PHINEAS H. ADAMS, Jr., and ORSEMAS T. X. ADAMS, citizens of the United States, residing at Chicago, Illinois, have invented certain new and useful Improvements in Apparatus for Use in De-' .March 5, 1889; and our invention consists in the features and details of construction hereinafter described and claimed.

In the drawing We have represented a vertical longitudinal section of ourimproved apparatus, with the running-gear in elevation.

In making our improved apparatus for decomposing chemical compounds, metallic salts, or salts of metals and desulphurizing ores we make two receiving-vessels A and B,

constructed and adapted to receive the substances to be treated when in a molten condition. These receiving-vesselsv may be made in such a way as will secure the. required strength and reduce the conduction of heat from the interior vto the exterior, and in other respects so made as will be calculated to subserve the end in view and permit of their being rotated at a high rate of speed for the separation of particles of different degrees of density in the matter treated. Many of these parts and the details of their construction, as they do not form the special subject-matter of our present claims, need not be more fully described, as they will be sufficiently understood from an inspection of the drawing. The receiving-vessels, however, are intended to be rotated in a horizontal instead of a vertical position and in special relation to each other, as hereinafter described.

The vessel B is arranged to be supported and rotated on an actuating-shaft C, substantially the same as in our patent above remit the discharge end of the vessel A, so that ferred to, except that we do not in the present case show the yieldable connections described in our other patent. The vessel A' is arranged with its discharge end open and extending through the end of the vessel B, and preferably slightly into the same. We prefer that the opening throughthe end of the vessel B should be large enough to freely adit may be easily inserted or removed, and by extending the discharge end of the vesselA slightly into the vessel B, as shown in the drawing, the material treated will be thrown off or discharged at a tangent by the action of centrifugal force as it enters the vessel B. This will have the effect of thoroughly loosening or separating the particles of matter and putting them in better condition for the renewed treatment to which they will be subjected in the vessel B.

The receiving end of the vessel A is supported and sustained substantially as in our other patent, except that we do not in the present case show the yieldable connections shown in that patent. In order to hold the vessel A in proper position and relation to the vessel B, we prefer to employ an annular case D, made of boiler-iron or other suitable material and firmly bolted to the ends of the vessels A and B, as shown, by the bolts at d. In this way the vessels A and B will be held securely together in. their proper relative positions, and yet the vessel A can be detached from the vessel B and removed from time to time, as occasion may require, to admit of the easy removal of the contents of the two vessels. It is obvious, of course, that more than twovessels could be arranged in the series, so that the material thrown off in treatment would pass from one to the other and repeatedly be subjected to a renewed treatment.

IVhere the receiving-vessels are arranged horizontally, the material is first treated in the vessel in which it is introduced and is finally discharged at the opposite end in the last vessel of the series. As the material is discharged it is caught in a surrounding curbing E and directed through a spout or other proper opening to a car or other receptacle to enable it to be carried away and deposited or otherwise disposed of as may suit the convenience of the operators. Where the vessels are arranged vertically, however, the material discharged is thrown ed at the mouth of the vessel through which it enters. This difference in operation necessitates a difierence in arrangement, as will be apparent on a comparison of our present improvement, above described, and our improvement shown and described in our application, Serial No. 302,666, filed March 9, 1889, in which the series of receiving-vessels are arranged in vertical relation to each other.

In operation the vessels A and B are rotated at a high rate of speed, so as to develop a great amount of centrifugal force. As the molten material enters the vessel A, it will be subjected to this force, and the heaviest particles in the matter treated will pass to the sides of the vessel, while the lighter particles, according to their specific gravity, will be ranged in order toward the center. As the material continues to be introduced, the accumulation of the heaviest particles toward the sides will displace the lighter particles until the vessel is sufficiently filled with material to enable it to begin discharging into the vessel B. As the operation continues, the material discharged into the vessel B will again be subjected to the action of centrifugal force and the heaviest particles again range themselves around the sides. The lighter particles will be displaced as the heavier particles enter, and the lightest portion of the material, which has been deprived of the valuable particles, will be discharged through the side openings, as represented in the drawing. In this way we not only secure the most complete and perfect separation of the valuable from the worthless portion of the material treated, but we separate the particles saved in the order of their specific gravity, which ordinarily represents the order of their relative value. After a sufiicient amount of valuable material has been collected in the receiving-vessels their rotation is discontinued and their contents emptied in some convenient receptacle, where they may be preserved and resmelted.

\Vhat we regard as new, and desire to secure by Letters Patent, is

1. In an apparatus for decomposing metallic salts or salts of metals and desulphurizing ores when in a molten state, the combination of a series of two or more horizontal revoluble receiving-vessels adapted to receive molten material to be treated, having the discharge end of each receiving-vessel, except the last, opening into the receiving end of the next adjacent vessel, whereby the material treated is successively carried by the action of centrifugal force from the vessel in which it is first treated to the next adjacent vessel to deposit and retain the heaviest particles of the material in each vessel in which it is treated, the first of the series of receiving-vessels having an opening for the introduction of the material to be treated, and the last of the series having an opening for the discharge of the same, a revoluble actuating-shaft rotating said vessel as it revolves, and means for rotating the actuating-shaft, substantially as described.

2. In an apparatus for decomposing metallic salts or salts of metals and desulphurizing ores when in a molten state, the combination of a series of two or more horizontal revoluble receiving-vessels adapted to receive molten material to be treated, arranged with the neck or mouth of each vessel, excepting the last, extending to the next adjacent vessel to dis charge the material treated into such vessel by the action of centrifugal force, whereby the material is successively treated in diiferent vessels and a part deposited and retained in each, the first of the series of receivingvessels having an opening for the introduction of the material to be treated, and the last of the series having an opening for the-discharge of the same, a revoluble actuatingshaft rotating said vessel as it revolves, and means for revolving the actuatin -shaft, substantially as described.

3. In an apparatus for decomposing metallic salts or salts of metals and desulphurizing ores when in a molten condition, the combination of a series of two or more horizontal revoluble receiving-vessels adapted to receive molten material to be treated, arranged with the neck or mouth of each vessel, except the last, extending to the next adjacent vessel to discharge the material treated into such vessel by the action of centrifugal force, and with each of the vessels separably attached to and rotatable with the next adjacent vessel, the first of the series of receiving-vessels having an opening for the introduction of the material to be treated, and the last of the series having an opening for the discharge of the same, a revoluble actuating-shaft rotating said vessel as it revolves, and means for rotating the actuating-shaft, substantially as described.
